Experienced mechanics share their insights in answering this question :
A noise diagnostic should pinpoint the specific fault especially as your indicating that the noise is limited to one corner of the vehicle, that is the right rear. If the noise is that localized, the cause will be relatively easy to find. Different people report noises differently of course, but "noise" generally from that area is due to brake issues, wheel bearings, loose struts, wear in the control arm bushings, other loose suspension parts and even loose lug nuts. The exhaust system will be checked, too, to be sure the pipes are not hitting the body, causing noise. As far as your issues with the steering wheel, this may be a separate issue. A certified YourMechanic technician can be dispatched to your location to inspect your steering system and suggest what the issue may be.

Worn Ball Joints

Ball joints enable the movement of the suspension control arms and steering knuckles. To move smoothly, it`s crucial that these joints remain lubricated at all times. If they become dry, they may start making squeaking or crunching noises when you turn the steering wheel at low speeds.

Low Power Steering Fluid: If you hear a squealing noise while turning the steering wheel, it may be an indication that the power steering fluid is low. Fluid may become low because of a leak. You can check under the engine for leaks by looking for red or pink liquid, the typical color of most power steering fluids.
Reasons Your Car Makes a Noise When You Turn the Wheel

Power Steering Pump: Also heard at low speeds, this sound is most often described as a whining sound that seems to be coming from the engine. CV Joints: If you notice a crunching noise when turning at high speeds, the main culprit is usually the CV joints.

Yes one of the most common symptoms of low power steering fluid besides harder turning is the noise. When the pump is low on fluid it can start to experience cavitation, which means air in the fluid pump causing damage. It will sound like a loud grinding, groaning, or binding noise.
A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.
When the Rack and Pinion Fails. There are a few ways you can tell if your steering gear is failing, such as excess noise, movement, effort or leaks. When you`re turning the steering wheel and it seems to be looser or tighter than the rest of the rack, you could have a flat spot or notch in the steering.
Power steering pump noise is one of the most identifiable sounds your car can make when it is broken. There can be a lot of clunks, squeaks or hums that can indicate a wide variety of other problems, but a whining power steering pump us usually very distinctive.
A low fluid level is the most common cause of power steering noises. The power steering fluid reservoir is small and many people don`t think to check it very often, so it won`t take much fluid loss to cause a problem.
Causes of Strange Sounds When Turning the Wheel

Suspension Joints: Often heard at lower speeds, creaking, clunking, or popping is an indication of worn-out suspension joints. Power Steering Pump: Another low-speed sound, a whining noise can often diagnose an issue with the power steering pump.

I can’t roll the rear passenger window up from either the drivers side or the passenger side. Could it be the regulator rather than the switches?

I did my brakes on my santa fe all except the rear passenger rotor. this morning the e brake on the rear passenger side locked up
ANSWER : The cable that you are referring to is made of ordinary steel and thus is subject to a lot of rust and corrosion. If rusted, it is possible that the cable is simply failing to retract in the cable sheath, even though you have released the emergency park. If you would like this e-brake failure to be inspected and resolved, the recommended service is parking brake cable replacement. The responding certified mechanic will inspect the e-brake system and if the cable is faulty, recommend replacement. If the fault is not in the cable, but instead in another system component, of course the mechanic will alternatively identify the other fault. If you have additional questions, do not hesitate to follow up.

You may spray a dish washing liquid and water solution on the components and anywhere you see a bubble will you know that you definitely have an air leak.

A technician from YourMechanic can come to your car’s location to inspect the issue and replace any faulty components as necessary.

Driver side door lock button not working, and passenger side sliding door makes a buzzing noise
ANSWER : Hi there. These door issues are common on this vehicle. Most of the time the main issue is the master door lock switch on the driver door. It sounds like you already replaced that. As for the sliding door problem, most of the time, this is a failure within the door module or it can be a connection issue.

I typically take the door apart and check the connections on the module and inside of the door just to make sure that there is nothing apparent in there. If the connections and the wiring are fine, then I use a scan tool to check the module to see what the inputs and outputs are doing. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your door problem and recommend a repair.

My heater is blowing air through the driver side air vents but is blowing cold air through the passenger side and rear console ven
ANSWER : Hi there:

Climate controlled vehicles have multiple electrical relays that open and close vents to maintain the desired temperature. In some instances, these relays can wear out overtime. However, it’s also common for debris to clog up vents (especially side vents) which may restrict the flow of cool air. The best way to determine why your AC is not working efficiently, it might be best to have a professional mechanic complete a AC inspection; so they can pinpoint the source of your issues and recommend the right repairs.

I was told that my passenger side rear brake caliper was locked up.
ANSWER : To perform a full overhaul of the braking system, you should replace the pads on the rear, the locked caliper, possibly the pads on the front if they are worn and flush out the dirty overheated brake fluid. If the rear rotors meet a specific thickness measurement, they may machined or resurfaced to have a fresh new surface for the new pads. You should at least have the stuck caliper replaced, rotors machined or replaced and replace the brake pads on the rear to make the vehicle safe again. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your braking system and offer a more personal repair estimate for your concerns.

Power mirror on passenger side will not retain it’s setting driver side works perfect.
ANSWER : A technician with an advanced scan tool can verify the issue. The mirror system is complex and involves many modules. The Body Control Module is a possible cause, but it’s doubtful; replacement requires reprogramming, which requires special equipment. I would check the driver’s and passenger’s door modules; toggle or move the switch on the driver’s side to see if it causes the problem, and ensure that the mirror glass itself is not loose on the passenger’s side mirror assembly.

Without diagnosing the problem with advanced equipment, the issue is hard to diagnose. A qualified YourMechanic technician can show up to the location of your vehicle with a scan tool to inspect and diagnose your power mirror issue.
